Description

Memory card and card reader

The present invention relates to a memory card and a card reader, and more particularly to a memory card having a memory component and a control component, and a card reader for reading a memory card.

With the rapid development of electronic products such as digital cameras, video cameras, mobile phones, personal digital assistants (PDAs), video players and game consoles, memory cards that are small in size, high in capacity, and easy to carry are often used as storage for such electronic products. The media is used to store many valuable materials of the user, such as personal data, private photos or audio and video files.

Please refer to FIG. 1A and FIG. 1B simultaneously. FIG. 1A is a schematic bottom view of the memory card 100 in the prior art, and FIG. 1B is a diagram showing the memory card 100 of FIG. 1A in the prior art. A schematic cross-sectional view.

The circuit board 110 has a first side 111 and a second side 112 opposite to each other. The memory component 120 is located on the second side 112 of the circuit board 110 and is used to store a data 121. The control element 130 is located on the second side 112 of the circuit board 110 and is used to control the memory element 120 to read the material 121. The contacts 140 are located on the first side 111 of the circuit board 110. The first conductive path 151 is electrically connected to the memory element 120 and the control element 130. The second conductive paths 152 are electrically connected to the control element 130 and the contacts 140.

The first cover 161 is combined with the second cover 162 to form an accommodating space 163, the circuit board 110, the memory component 120, the control component 130, the contacts 140, the first conductive paths 151, and the like. The two conductive paths 152 are all located in the accommodating space 163. The first cover 161 has an opening 164 that exposes the contacts 140.

Referring to FIG. 2, a cross-sectional view of a card reader 200 in the prior art is shown. The card reader 200 includes a housing 210, a circuit board 220, a plurality of terminals 230, a control component 240, a transmission interface 250, a plurality of first conductive paths 261, and a plurality of second conductive paths 262.

The housing 210 has a slot 211. The circuit board 220 is located in the housing 210 and has a first surface 221 and a second surface 222 opposite to each other. The terminals 230 are located on the second surface 222 of the circuit board 220. The control element 240 is located on the first surface 221 of the circuit board 220, and the transmission interface 250 is located on the outer surface of the housing 210. The first conductive path 261 is electrically connected to the terminal 230 and the control component 240 . The second conductive path 262 is electrically connected to the control component 240 and the transmission interface 250 .

Referring to FIG. 3, a cross-sectional view of the card reader 200 reading the memory card 100 in the prior art is shown. When the card 121 of the memory card 100 is read by the card reader 200, the user needs to insert the memory card 100 into the slot 211 so that the contacts 140 of the memory card 100 respectively contact the terminals 230 of the card reader 200.

Next, the control component 240 of the card reader 200 controls the control component 130 of the memory card 100, causes the control component 130 to control the memory component 120, and sequentially passes the data 121 through the first conductive path 151 of the memory card 100, and the second conductive path. 152 and the contact 140 are transmitted to the card reader 200, and then the data 121 is sequentially transmitted to the external electronic device via the terminal 230 of the card reader 200, the first conductive path 261, the second conductive path 262, and the transmission interface 250 (Fig. Not shown), such as a computer or display device. Thereby, the card reader 200 can read the data 121 of the memory card 100 and display the contents of the material 121 by the external electronic device.

A disadvantage of the above-mentioned prior art is that only the contact 140 of the memory card 100 is exposed at the opening 164, and other components are covered in the first cover 161 and the second cover 162. When the control component 130 of the memory card 100 fails to operate normally, such as the damage, failure, short circuit, failure, poor contact or loss of function of the control component 130, the card reader 200 cannot pass the data 121 of the memory component 120 through such The contact 140 is read out, and the memory card 100 needs to be sent back to the maintenance vendor for rescue to read the data 121.

Moreover, when the maintenance manufacturer or the maintenance personnel processes the memory card 100, the first cover 161 and the second cover 162 of the memory card 100 are usually disassembled, and the control element 130 that cannot function normally is replaced with a new one. The control element, or the memory element 120 is unsoldered, and the data 121 of the memory element 120 is read by a special card reader (not shown).

As a result, it takes several days and expensive expenses in the process of repairing the memory card 100 or the rescue material 121. Moreover, when the first cover 161 and the second cover 162 are disassembled, the first cover 161 and the second cover 162 are damaged and cannot be combined again.

At the same time, when the maintenance personnel unwrap the memory element 120, it is easy to damage the data structure or electronic circuit in the memory element 120, and the internal data 121 cannot be read permanently. Moreover, when testing the compatibility of the memory element 120 and the control element 130, the data structure in the memory element 120 may be changed, resulting in a permanent loss of part of the data 121.

Also, the biggest drawback is that the repair vendor or maintenance personnel can glimpse important information or private photos in the memory card 100, and may upload it to the Internet, reveal it to the outside, resell it to others, or threaten to intimidate, thus seriously affecting the use. Privacy or personal reputation.
